The rows of each set of three are preferably staggered with respect to each other in order to give the desired distribution of the discharging liquid. The fixed end of the support 13 is connected to and communicates with a pipe 21, here shown as vertical--y ly disposed and terminating at'its lower end in a connection 22 with the discharge end of a pump 23. A valve 24 may be mounted uponthe end of the pipe 21 for drain purposes as will be 11nderstood. The pump l23 is driven from any suit- `able source of'power and has an intake pipe 25 from the support 13 at predetermined intervals inv order to change the position of the hanging material with respect to the support a lifting rod 26 is provided and supported at its ends respectively in two hanger arms 27 which extend radially from the supporta suicient distance to give the desired lift to the material when the rod is revolved aboutthesupport 13 as an'axis. The arm 27 at the free end of the support 13'is journalled upon the end of the support 13 `in any suitable manner. The other arm 27 is connected to a tubular hub 30 which is keyed as shown at 31, or otherwise made fast to a sleeve 32 which is supported for rotation .upon a bearing carried as a part of the bracket 14. This sleeve 32, as here shown, has a spiral gear 33 formed thereof and in meshwith a worm gear 34 upon the driven counter-shaft 35. These intermeshing gears which form the means for transmitting motion to ,the arms '27 are suitably housedwithin case plates 36 and acase cap 37 as will be understood.

' Preferably also thrust collars 38v are arranged at 'opposite sides respectively of the gear, 33 as will begevident. In connection with the arms 27 it should be noted that the hub 28 of each is axial-y lyA extended so that the inner face thereof is brought substantially into the` vertical plane 1.'. which includes the flanges 19 at v the opposite ren dsrespectively of the support 13.

This eX- tended yportion of the hubs'28 is of curved contour so that,v during the lifting movement of the arm the `convex face thereof willserve as a stop and guide to prevent the yarn or vother material from movingendwise on the rod and also insur-y ing that it be directed or guided onto the adja cent wide curved face forming the upper portion of -the respective flanges of the support :13. The counter-shaft 35 is driven through suitable gearing 41 from a motor shaft .42 of .the motor43 which is suitably mounted upon a part of the main frame of the machine. Preferably the mtor 43 is of the two phase typeand its operation f is under the control of a magneticfswitch 44 as will be explained.y s A. 1 l For the purpose. of controlling the operation of the motor 43 sothat the material lifting rod 26 will rotate in a predetermined manner`v a 75h magnetic control coil 45 forthe switch 44 is included in an electric circuit having a conductor 46 leading from one side of the coil 45 to the positive pole of a single phase source of current, while the opposite side of the coil 45 is connected by a conductor 47 which connects the stationary contacts 48 and 49 of the switches 50 and 51` in parallel relation. A branch .conductor 52 leads from the conductor 47 to 'a Contact 53 which forms one terminal of a circuit select'- ing switch of which 54 is another stationary contact and 55 is the movable contacter `ar vranged to move into contact with one of the other contacts 53 or 54 according to requirei ments. The contact 54 is connected by a conductor 56 to the contacter 57' of the switch 51 and this latter is arranged to engage the contact 49 to closek this` branch of the circuit. Normally the contactor 57 is held flexed against its spring tendency to close the contacts by an extension wiper 58 preferably formed integral `therewith and arranged to travel upon the periphery of a timing cam 59 and which is provided with a gap 60 of such a depth as to insure the wiper 58 moving radially inward when it leaves the periphery ofthe cam 59 to close the circuit between the contactor 57 and the contact 49. The circumferential length of thisy gap 60 is sufficient to insure a closing of the circuit lcng enough so that the rod 26 starts upon its rotation about'the support 13. The cam 59 is preferably driven by a constant speed induction motor of any well known type and need not here be shown nor specifically described since all that is required for an understanding of the present invention is that this .cam 59 ris driven at a constant speed. The contact 54 is also connected by a'conductor 6l to the movable contacter 62 of the switch 50 and this is arranged through its spring action to close the circuit aty this point whenever the wiper element 64 of the contacter 62 is picked up by the periphery of a rotatable limitl cam 65 having` a gap v66 of sufficient depth to allow the contac- Fig. 6 with both switches open andthe wiper 58 just ready to drop into the gap 60 of the cam 59 to close the circuit through the coil 45, while the' wiper element 64 is in the gap 66 and the two contacts 48 and 62 are spaced apart. The mounting V-for the limit cam 65 consists of a shaft 67 suitably journalled in a supplemental housing 68 and on this shaft 67 is a gear 70 meshing with a gear 7l upon the counter shaft 35. The gear ratio is such as tocause the limit cam 65 to rotate in synchronism with the arms 27 and the initial setting of the limit cam is such that the gap 66 is at its lowest position vwhen the rod 26 is at rest in the lowest position.

will ragain'ibegsat the point where!thaiwiper;` 64.5`

can drop into it to break the circuit between the Contact 48 and the contacter 62. The breaking of this circuit at once deenergizes the coil 45 to thereby break the motor circuit and stop the motor. Since the magnetic brake '72 is also controlled by the circuit which energizes the motor 43 the coil of the solenoid '77 will be deenergized and thereby release the control levers so that the brake shoes instantly grab vand hold the wheel 75 lwhich is fast upon the shaft 42 to stop the rod 26 in its predetermined position.

. When it isdesired to rotate the lift rod 26 continuously the contacter 55 is moved from the contact 54' to contact 53 and thereby closes a diierent circuit through the electro-magnet 45 and the' latter becomes continuously energized. The circuit so closed is from the contactor 55 to contact 53, conductor 52, conductor 47, coil 45,

'conductor 46 through the source of current to capable of selective operation so `that for some kinds of goods the rod 26 will rotate continuously and in other classes of goods it will rotate only at predetermined intervals. All rotation of the lift rod? 26 can be dispensed with if' desired by placing lthe contactor 55 in a neutral position where it is out of contact with both contacts 53 and 54.
